We used electronic medical record (EMR) analysis to determine errors in operating room (OR) time utilisation. Over a two year period EMR data of 44,503 surgical procedures was analysed for OR duration, on-time, first case, and add-on time performance, within 19 surgical specialties. Maximal OR time utilisation at our institution could have saved over 302,620 min or 5,044 hours of OR efficiency over a two year period. Most specialties (78.95%) had inaccurately scheduled procedure times and therefore used the OR more than their scheduled allotment time. Significant differences occurred between the mean scheduled surgical durations (101.38 ± 87.11 min) and actual durations (108.18 ± 102.27 min; P < 0.001). Significant differences also occurred between the mean scheduled add-on durations (111.4 ± 75.5 min) and the actual add-on scheduled durations (118.6 ± 90.1 minutes; P < 0.001). EMR quality improvement analysis can be used to determine scheduling error and bias, in order to improve efficiency and increase OR time utilisation.
我们采用电子病历（EMR）分析来确定手术室（OR）时间利用方面的差错。在两年时间里，对19个外科专业的44,503例外科手术的EMR数据进行了分析，以了解手术时长、准时性、首台手术以及追加手术时间的表现。在两年时间里，我们机构手术室时间的最大利用率本可节省超过302,620分钟或5,044小时的手术室效率。大多数专业（78.95%）安排的手术时间不准确，因此使用手术室的时间超过了其预定分配时间。平均预定手术时长（101.38±87.11分钟）与实际时长（108.18±102.27分钟；P<0.001）之间存在显著差异。平均预定追加手术时长（111.4±75.5分钟）与实际预定追加手术时长（118.6±90.1分钟；P<0.001）之间也存在显著差异。电子病历质量改进分析可用于确定排班误差和偏差，以提高效率并增加手术室时间利用率。
